[0031] Example 1

[0032] Please see Figure 1-5 A pressing device for an outboard engine cylinder head oil seal includes a pressing platform table 1, a pressing assembly and a pressing limiting assembly mounted on the pressing platform table 1.

[0033] The press-fit assembly includes an oil seal press head 7 that cooperates with the oil seal of the outboard engine cylinder head 23, a press plate 6 that presses against the oil seal press head 7, and a press-fit cylinder 5 that drives the press plate 6 to move.

[0036] The pressing platform table 1 is equipped with a solenoid valve 3 that works with the pressing cylinder 5, a switch box 10 that controls the start and stop of the device, and a switching power supply 2 that supplies power to the solenoid valve 3 and the switch box 10.

[0037] The switch box 10 is equipped with a manual switch knob 13 and an automatic return switch button 14, which are connected to the switching power supply 17 via switching power supply lines.

[0038] The solenoid valve 3 is connected to an air source inlet pipe 15 that connects to an air source, two cylinder inlet pipes 16 that connect to the press-fit cylinder 5, and a solenoid valve power line 17 that connects to the switching power supply 2.

[0039] The pressing cylinder 5 is mounted on the pressing platform table 1 by two cylinder support plates 4, and the pressure plate 6 is mounted on the piston rod end of the pressing cylinder 5.

[0040] Example 2

[0041] The number of press-fit limiting plates 8 is two, and the two press-fit limiting plates are arranged in parallel. The force-bearing support plate 9 is vertically installed on the corresponding adjustment limiting groove 11 of the two press-fit limiting plates.

[0042] The surface of the force-bearing support plate 9 corresponding to the outboard engine cylinder head is provided with a polyurethane protective pad 12, the length of which is matched with the distance between the two press-fit limiting plates 8.

[0043] Example 3

[0044] The press-fitting platform table 1 includes a top plate 18, four supporting columns 19 installed at the bottom of the top plate 18, four supporting crossbeams 20 installed in the middle of the four supporting columns 19, and four reinforcing crossbeams 21 installed at the top of the four supporting columns 19. A mounting plate 22 is provided between one of the reinforcing crossbeams and two of the supporting columns, and the solenoid valve 3 and the switching power supply 2 are both mounted on the mounting plate 22.

[0045] Example 4

[0046] The supporting column 19, supporting beam 20 and reinforcing beam 21 are all made of aluminum profiles, and the top plate 18 is made of aluminum plate.

[0047] The specific functions of each main component in this utility model are as follows:

[0048] 1. Pressing platform table: Designed with aluminum profiles, it serves as the basic frame for the pressing device, connecting and supporting the other components of the pressing device for pressing operations;

[0049] 2. Switching power supply: Converts high-voltage electricity into low-voltage electricity to provide power for solenoid valves and switches;

[0050] 3. Solenoid valve: Used to control the movement of the cylinder. It controls the flow of air through electrical signals, thereby driving the cylinder to perform pressing or retraction operations.

[0051] 4. Cylinder support plate: Supports and fixes the cylinder to ensure that the cylinder remains stable during the press-fitting process and does not shift or shake.

[0052] 5. Press-fit cylinder: Provides the power required for press-fitting, and drives the pressure plate or oil seal pressure head to move through air pressure to complete the press-fitting of the oil seal;

[0053] 6. Pressure plate: Connected to the cylinder, it moves with the cylinder and is used to press the oil seal evenly into the cylinder head;

[0054] 7. Oil seal press head: A component specially designed for press-fitting oil seals. Its shape and size match the oil seal groove of the oil seal and cylinder head, ensuring that the oil seal can be accurately and tightly pressed into the groove. Different oil seal press heads can be replaced to match the cylinder heads of different models.

[0055] 8. Press-fit limiting plate: Ensures the stability of the cylinder head during the press-fit process. It is used to limit the movement range of the pressure plate or oil seal pressure head, and ensures that the oil seal and cylinder head are not over-pressed or damaged during the press-fit process. The position of the force support plate on the limiting plate can be adjusted during press-fit for different models.

[0056] 9. Load-bearing support plate: During the press-fitting process, it provides support for the cylinder head, stabilizes the press-fitting process, and ensures that the cylinder head oil seal can be press-fitted into place within the movement range of the oil seal press head. It has a polyurethane protective plate on it, which can protect the cylinder head during the press-fitting process.

[0057] 10. Switch box: Contains switches and buttons that control the operation of the entire device, used to start and stop the pressing operation and perform other necessary controls;

[0058] The operating steps of this utility model are as follows: When using the device, connect the cylinder head oil seal pressing device to an external power source and air supply; determine the outboard engine model to be pressed, select the corresponding oil seal press head and load-bearing support plate, and install the load-bearing support plate on the limiting plate; place the outboard engine cylinder head to be pressed onto the pressing platform table, ensuring the oil seal face of the cylinder head faces the cylinder pressing direction, and the other side of the cylinder head contacts the load-bearing support plate. The load-bearing support plate has a polyurethane protective plate, which protects the outboard engine cylinder head from scratches during the pressing process; insert the cylinder head oil seal to be pressed onto the oil seal press head (tooling), determine the pressing direction of the oil seal lip according to the cylinder head oil seal pressing process, and then insert the oil seal press head (tooling) and cylinder head oil seal together into the oil seal mounting hole on the cylinder head (the hole is fitted with a cam). The camshaft diameter is the same as the inner ring diameter of the oil seal, and one end of the oil seal pressure head fixture has the same diameter as the outer ring diameter of the camshaft. This ensures that the oil seal pressure head is coaxially inserted into the camshaft mounting hole of the cylinder head, and also ensures that the cylinder head oil seal is coaxial with the cylinder head mounting hole during the pressing process. The switch box button is activated to press the cylinder head oil seal. The switch box has both manual and automatic return knobs. (The switching power supply is connected to an external power source, converting it to low-voltage electricity to power the solenoid valve and switch box. When pressing begins, the switching power supply receives an electrical signal from the switch box to provide an on / off signal to the solenoid valve. The solenoid valve controls the external air supply to the cylinder, controlling the cylinder's pressing and retraction. The cylinder drives the pressure plate, and the large force-bearing surface of the pressure plate ensures that the oil seal pressure head is evenly stressed.) After the oil seal pressing is completed, the oil seal pressure head (fixture) is removed, and this process is repeated.

[0059] This utility model's cylinder head oil seal press-fitting device is mainly used in the press-fitting of cylinder head oil seals for outboard motor engines. It is suitable for use in factory production when there are many batches and small quantities per batch. When there are many outboard motor models and the cylinder head size range is relatively large, the traditional vertical cylinder head oil seal press-fitting method cannot meet the needs of factory use. The cylinder head oil seal press-fitting device designed by this invention is a horizontal cylinder head oil seal press-fitting device, which can be used for press-fitting cylinder head oil seals of different models. It can also accommodate a relatively large range of cylinder head sizes, and the press-fitting is stable and reliable, creating favorable conditions for improving the quality and performance of outboard motors.

[0060] Compared with traditional pressing methods, the cylinder head oil seal pressing device of this utility model has the following advantages:

[0061] 1. Modular Design: To reduce costs and improve production efficiency, this outboard motor cylinder head oil seal press-fitting device adopts a modular design, making the device a standard parts assembly. If a module has a problem, it can be replaced individually, reducing maintenance costs. At the same time, the modular design also makes it quick and convenient to change different models of oil seal press heads for different outboard motor models, and then press-fit the cylinder head oil seal after adjustment.

[0062] 2. Improved production efficiency: The outboard motor cylinder head oil seal pressing device adopts an automatic return pressing button and a semi-automatic return pressing button, ensuring a stable pressing cycle. The mature automation integration technology (PLC) avoids operator errors during the pressing process. Moreover, the device is a one-button operation, which is convenient for operators and improves pressing production efficiency.

[0063] 3. Enhanced compatibility: Taking into account the differences in cylinder head size among different outboard motor models, this outboard motor cylinder head oil seal press-fitting device is designed with a limiting plate. The limiting plate has different limiting grooves, and a force-bearing support plate is placed in the limiting groove. This allows for compatibility with different models of outboard motors for adjusting the press-fitting of cylinder head oil seals. Moreover, this device adopts a horizontal press-fitting method, which increases the press-fitting movement range and can better accommodate cylinder heads of a wider range of sizes.

[0064] 4. Press-fit protection of the workpiece: The oil seal press-fit device for the outboard motor cylinder head adopts an oil seal pressure head guide device to ensure that the oil seal and the cylinder head shaft hole are coaxially aligned during the oil seal press-fit process. This device provides pressure to the cylinder, and the cylinder pressure is stable to avoid excessive pressure from damaging the parts. In addition, the force support plate of the cylinder head is equipped with a polyurethane protective plate, which can better protect the cylinder head from damage during the press-fit process.

[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
